대표청구항 ▼

What is claimed is: 1. An internal combustion engine, comprising: a cylinder carrier, comprising: a plurality of cylinder mounting modules; and a plurality of main bearing bulkheads interposed between and interconnecting adjacent ones of said cylinder mounting modules; a crankshaft mounted to said main bearing bulkheads, with said crankshaft having a longitudinal centerline; and a plurality of cylinder assemblies mounted to said plurality of cylinder mounting modules, with each of said cylinder assemblies comprising: a cylinder bore portion which does not contact any of said main bearing bulkheads; a cylinder head having at least one intake port and at least one exhaust port; a piston slidingly housed within said cylinder portion; and a connecting rod mounted to said crankshaft. 2. An internal combustion engine according to claim 1, further comprising a plurality of structural rails extending longitudinally along the periphery of said cylinder carrier parallel to said crankshaft centerline, with said structural rails extending downwardly from a position above the centerline of the crankshaft to an oil pan. 3. An internal combustion engine according to claim 1, wherein each of said cylinder portions has a piston ring compression zone comprising a lower part of the cylinder. 4. An internal combustion engine, according to claim 1, wherein each of said cylinder mounting modules comprises a light alloy casting, and each of said main bearing bulkheads comprises a ferrous body. 5. An internal combustion engine, according to claim 4, wherein each of said cylinder mounting modules comprises an aluminum casting. 6. An internal combustion engine, according to claim 1, wherein each of said cylinder mounting modules comprises a light alloy casting, and each of said main bearing bulkheads comprises a light alloy body. 7. An internal combustion engine, according to claim 1, wherein each of said cylinder mounting modules comprises a ferrous casting, and each of said main bearing bulkheads comprises a ferrous body. 8. An internal combustion engine according to claim 1, wherein each of said cylinder portions comprises a cast metal body having a honed bore and an integral water jacket circumscribing a cylindrical wall containing said bore. 9. An internal combustion engine according to claim 8, further comprising a common rail system for introducing liquid coolant into the integral water jacket contained within each of said cylinder portions. 10. An internal combustion engine according to claim 8, wherein said bore contains a cylinder sleeve. 11. An internal combustion engine according to claim 1, further comprising a single camshaft extending parallel to said crankshaft centerline, with said camshaft operating at least one intake valve and at least one exhaust valve for each of the plurality of cylinder heads, with said camshaft operating said valves by means of a plurality of rocker shafts extending across an upper portion of each of said cylinder heads in a direction generally perpendicular to said crankshaft centerline. 12. An internal combustion engine according to claim 1, further comprising an exhaust manifold assembly, mounted to each of said cylinder heads, with said exhaust manifold comprising a plurality of branch passages for receiving exhaust from each of said exhaust ports, and with said exhaust manifold further comprising a plurality of separate, annular intake coolant passages for conducting coolant flowing from each of said self-contained cooling passages about an exterior portion of a mating one of each of said branch passages. 13. An internal combustion engine according to claim 1, further comprising at least one fuel injector mounted to each of said cylinder heads. 14. An internal combustion engine according to claim 1, wherein said at least one fuel injector comprises a diesel fuel injector. 15. An internal combustion engine according to claim 1, wherein said at least one fuel injector comprises a gasoline injector. 16. An internal combustion engine according to claim 1, wherein said at least one fuel injector comprises a natural gas injector. 17. An internal combustion engine according to claim 1, wherein said at least one fuel injector comprises a nitrous oxide injector. 18. A method for removing and re-installing an individual cylinder assembly of an internal combustion engine, comprising the steps of: removing a plurality of fasteners extending from a cylinder carrier upwardly through a cylinder portion and a cylinder head; lifting said cylinder head from said engine; lifting said cylinder portion from said engine; removing a wrist pin and a piston mounted upon a connecting rod for reciprocation within the cylinder portion; installing a new piston and wrist pin upon said connecting rod; installing a new cylinder portion upon said piston by sliding a piston ring compression zone of said cylinder portion over a plurality of piston rings carried upon said piston; seating said new cylinder portion upon a pilot diameter formed in the cylinder carrier; and mounting said cylinder head upon said cylinder portion. 19. A method for replacing crankshaft main bearing inserts in a reciprocating internal combustion engine, comprising the steps of: removing an oil pan mounted to structural rails at the bottom of the engine's crankcase; removing at least one structural rail extending longitudinally along a portion of the periphery of said cylinder carrier parallel to said crankshaft centerline, with said structural rail also extending vertically from a position above the centerline of the crankshaft to said oil pan; serially removing a plurality of main bearing caps from a cylinder carrier, while replacing the main bearing insert associated with each of said bearing caps; reinstalling said at least one structural rail; and reinstalling said oil pan.
